SNOW-GUARD FOR ROOFS.

SPECIFICATION forming part of Letters Patent No. 250,580, dated December6, 1881, Application filed September 9, 1881. (No model.)

To all whom it may concern:

Be it known that I, ANDREW D. RoeERs,

of the city and county of Worcester, and State of Massachusetts, haveinvented a new and useful Improvement in Snow-Guards for Slated Roofs;and I do hereby declare the same to be described in the followingspecification and represented in the accompanying drawings, of which-Figure l is a top view, and Figs.2 and 3 are sectional views, of part ofa slated roof with my improvement applied to it.

My invention has reference to the snowguard and its application to aroot, and is defined in the claims hereinafter made.

In the said drawings, A B O D denote the first, second, third, and.fourth of the courses of slating of a roof, E, the rafters of such roofbeing represented at a a a and their boarding at b.

The snow-guard is composed of a series of metallic screw-posts, F, a setof connection metallic wires, G, and a set of metallic guardplates, H,there being one of such plates to each post, which goes through theplate, the latter being soldered to the post or otherwise properlyconnected therewith, so that the connection shall be a water-tightjoint.The posts F, I arrange just above and closely to the upper edge of thefirst course of slates, and to go through holes efmade in the second andthird courses, and screw into the roof or through the boarding and intothe rafters. Each post has a male screw cut on it from its lower endupward the proper distance forthe post to enter the roof. Besides suchscrew, there are two or any other suitable number of holes, 0, madetransversely through each post for the reception of the connecting rodsor wires G, arranged as shown, they being secured in any proper mannerin or to the posts. Between the second and third courses of the slatesthe series of metallic guard-plates H is arranged. These guard-plates,by being soldered or fixed withwater-tight joints to the several posts,serve to intercept any water that may flow through the post-holes of thethird course of slates and prevent it from passing into the post-holesof the second course,such water, by means of the plates, being directeddown between the two courses of slates, from whence it will escapedownward without wetting the boarding. The guard-plates are not to befastened down otherwise than by the posts, such plate being free to movewith its post in case of said post being moved or bent laterally.

The snow-guard, constructed and applied to the roof and its courses ofslates in manner substantially as set forth, serves not only its1egitimate purpose of preventing snow or a person sliding down and offthe roof, but aids greatly in keeping the slates in place.

I would remark that the posts, connectionwires, and guard-plates may beotj iron coated with zinc or tin, or they may be of copper orcomposition metal, if preferable. They constitute a very cheap, durable,and effective snowguard when applied to a roof in manner as explained.

Between the posts I arrange a series of supporters, I, each of whichconsists of a strip of metal resting at its foot on the slating, andhaving holes made through it (the said strip) for reception of thewires, which go through the strip. Thus the strips serve to sustain thewires between the posts and prevent such wires from bending down orbeing broken.

\Vhat I claim as my invention is as follows, viz:

1. The combination of the series of screwposts and theirconnecting-wires with the guard-plates applied to the posts, as setforth.

2. The combination of the series ot'posts, provided with connectionwires or rods and extended through two courses of slates and screwedinto the roof, with such roof and slates and a series of guard-platesarranged between the said courses of slates and secured to the posts,all being substantially as set forth.

3. The combination of the supporters I withtheseriesofscrew-posts,theirconnecting-wires, and guard-plates, arrangedwith a roof and its slating, substantially as set forth.

4. The posts, connecting-rods, and guardplates, arranged and combinedwith a roof and its slating, substantially as specified.
